📝 Walkthrough

Walkthrough

This pull request adds three missing fields to the BillingPlan type in the @clerk/backend package. The avatarUrl, freeTrialDays, and freeTrialEnabled fields are added as public members to the BillingPlan class. The constructor signature is updated to accept these new parameters following the existing features field. The BillingPlanJSON interface is expanded with corresponding JSON mapping fields (avatar_url, free_trial_days, free_trial_enabled), and the fromJSON method is updated to populate these fields from the JSON data. A changeset entry documents this patch-level change.
